Hi All
Have a project in hand under which production (10G) instance needs to be upgraded without downtime. So, plan is to create logical DR for 10G instance and upgrade it to which application points later on this new upgraded database. Post upgrade of LDR to 11G and making it primary; Is it possible to have Logical DR configured on old db which is on 10G (10.2.0.5) getting synced from newly upgraded database (11.2.0.3.6)? This is required incase activity has to rollback and we need to move to old release, but want to ensure all delta is also available in 10G db; else there will be no rollback.
